Data transmission method and device using 8-10 bit conversion and successive plus and minus running disparity synchronous data words

摘要

In the case of transmitting upon converting the 8-bit word string data showing signal information to the 10-bit word string data consisting of word synchronous data, 8-bit word string data showing signal information is obtained and after inserting 2 each of the 8-bit word synchronous data and the 8-bit auxiliary word data to be converted to the 10-bit neutral word data, 8 to 10 bits conversion is conducted to the 10-bit word string data and transmitted; when converting the 8-bit word synchronous data to 10-bit word synchronous data, if the immediately preceding word data is the data having plus running disparity, it is converted to 10-bit word synchronous data having minus running disparity, and if the immediately preceding word data is the data having minus running disparity, it is converted to the 10-bit word synchronous data having plus running disparity. Thereby, in the case of reproducing the signal information at the receiving end, the necessary signal synchronization can be certainly obtained.
